• RE: AD7490: REFIN = 3V

    Hi, 

    Yes, the performance rspecification is tested and guaranteed using a 2.5V reference voltage. And I think the allowable range for specified performance is 2.5V +/1% only. There no specification for 3V reference. Having 3V will not damage the part but…

  • AD7490 Sampling Rate & Artifacts

    Hello,

    I am testing a design with an AD7490 and I'm a bit unsure on how to determine the sampling rate. Given VDD of 5V, per the datasheet a 20 MHz SCLK should be equivalent to a 1MSPS sampling rate. Does that mean it's a 20:1 ratio for the sampling…
